How To Choose a Prepaid Smart Electric Meter?
In addition to the metering function, the prepaid smart meter also has a special function that users need to pay for electricity before using electricity. If the user does not continue to buy electricity after running out of electricity, the power supply will be automatically cut off to stop the power supply. Therefore, prepaid electricity meters are welcomed by the majority of users. So how should you choose a prepaid smart meter? Here we recommend you start from three aspects: current specification, model and brand.
Current specification
The current mainstream current specifications of single-phase prepaid smart meters are 5(40)A and 5(60)A, which are suitable for residential users and rental users. Before selecting the current specification of a three-phase prepaid meter, it is necessary to confirm the measured voltage first, and consider the load type and load power to determine the required current specification and reserved space of the meter. The three-phase electricity meter is suitable for small and medium-sized businesses, industrial and mining enterprises, public facilities, and other occasions.
It should be noted here that some customers are wondering whether they can directly buy the largest current specification without considering the calculation of voltage and power. It is not recommended here, because the larger the current specification, the higher the price, and there will be a cost problem.
Model
The model of the prepaid smart meter is written with the fourth letter "Y", such as DDZY71, which means that the meter has a prepaid function. In addition, to distinguish between single-phase and three-phase, DD- means single-phase, DS/DT- means three-phase three-wire/three-phase four-wire. In terms of price, single-phase will be cheaper than three-phase, and there are not as many functions as three-phase. Users can choose a suitable meter according to actual needs.
Brand
Although there are various brands of prepaid smart meters on the market today. However, in terms of quality and after-sales service, it is recommended that users choose the current well-known brand meters in China, which also have a relatively wide overseas market.
